Three new N-Eupex couplings and optimised versatile parts

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new varieties. The new merchandise enable users extra flexibility in their techniques with out dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which offers even more

safety in the drivetrain in lots of applications. The coupling variant permits customers to

specify a maximum torque in order that crucial torques for the motor and output machine

aren’t transmitted. Machines and systems are protected from overload and

damage, thus considerably increasing system availability.
With the N-Eupex B plus clamping element, Flender introduces a second new

coupling that ensures frictionally engaged clamping connections. In this case, the

plain, cylindrical machine shaft finish is connected to the coupling hub via a clamping

connection with no feather key and repair capacity is elevated. For example,
assembly or replacement of worn elastomers may be carried out much more simply.
No connecting machine components have to be moved, the time required is halved

and so is the downtime of the machine.
With the N-Eupex DKS, a brand new double-cardanic coupling is introduced as a “short

version” into Flender’s modular system. While the DK type, which was launched in

2020, addresses the pump market with normal expansion items for normed shaft

distances, the DKS is the shortest attainable double-cardanic answer for the market.
ไดอะแฟรม ซีล shortened overall size enables cost-optimized use with a small shaft distance

dimension without shedding some great advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition

to the beforehand used rubber elements made from NBR, Flender now also presents

elastomers made of thermoplastic polyurethane (TPU). Following the torque

increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU

packings permits the ability density to be increased by one other 20 % on

common. For sizes 300 and above, the acquainted NBR elastomer is combined with

material inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our development engineers are

systematically engaged on rising the number of combinations even further. The

2022 enhancements give our users a extensive range of sustainable choices for

optimizing their machines and systems much more and lowering maintenance,”

explains André Artmann, Head of Coupling Sales.
